Combined pedal force switch and position sensor |
May 16, 1995 |
| A pedal bracket assembly translates pedal motion into a first switching motion without change of position being sensed by a position sensor. Additional pedal motion does not further change the switch position, but is translated into motion sensed by the position sensor. In this way, the |
